Also, I heard the "human cockfighting" metaphor used again in the Rogan vid. I think that is about the worst analogy to use. In cockfigthing, the birds get no choice and have razorblades attached to them to cause more offensive damage. In MMA, these guys choose to fight. They do it in a mostly professional manner (what Mir said about hoping to kill Lesnar notwithstanding) and they do so without attaching razorblades to their bodies to inflict more bloody injuries.
